A METHOD FOR ESTABLISHING END-TO-END DATA TRANSMISSION PATHS USING THE ICMP BASED HOP-BY-HOP RESOURCE RESERVATION SIGNALLING PROTOCOL

摘要

The invention provides a data transmission network having a number of network nodes, which include routers and end terminals, in which end-to-end data transmission paths are established between end terminals using a hop-by-hop resource reservation signalling protocol (called a RING - Reservation pING protocol) and in which an Internet Control and Management Protocol (ICMP) is used for message transportation. The network uses ICMP ECHO and ICMP REPLY messages (PING) for message transportation. The IP flow, specified in the reservation message, is provided with a hard QoS in the RING-aware part of the network and a soft QoS in the DiffServ capable domains.
